model for dampening of pendulum given by: y''+by'+siny=0
prepare simulink models that will take value b from a constant block and
a)plot the numerical solution of this differential equation with initial conditions y(0)=0 and y'(0)=4 from t=0 to t=20
b)do the same linear approx. for y''+by'+y=0

compare linear and nonlinear behavior for values b=1, 1.5, and 2. Interpret what is happening physically in each case.


will pay fg for code or help
